Extended length heavy buffer for blowback 9mm AR's. Hollow steel body filled with lead shot to eliminate bolt bounce in blowback systems. 

• Machined steel body
• 4 inch over all length
• Black nitride coated.
• smooths recoil impulse, reduces perceived recoil
• Eliminates "bolt bounce" and the out of battery issues associated 
•  7.5 ounce weight
• weight can be reduced by removing internal mass, but usually not required

We are running another batch of buffers now (11/29/21) hope to have in nitride tomorrow.
